This is basically impossible, since boot_args is fixed in size by palo,
initialized to zero, and length checked in the bootloader. It's also
only 256+4 bytes compared to the 1024 bytes set aside for
boot_command_line.

That said, it's harmless to use strlcpy here, and obviously (more)
correct. Thanks!
